IPC: B41J5/30
Filed: 1988-02-15
Abstract: PURPOSE:To realize a high-speed data forming for a plurality of image memories, by a method wherein a logical operation is conducted between the read data from the two or more memories which can be simultaneously accessed with the same address and the data written from the external, and the result is written into a plurality of memories. CONSTITUTION:RAMs 4, 5 store image data, and a timing generating circuit 1 generates various timing signals for accessing to memories by a read/write mode signal 3 and a start signal 2 sent from a CPU. By the read mode signal from the CPU, the CPU can fetch the bites of read data 14 and 15 alternately from the RAMs 4, 5, and can impart image data at substantially the same time. A logical operation circuit 6 conducts a logical operation with the input of the read data 14, 15 and image data 11 from the CPU. The results 16, 17 are written in the RAMs 4, 5 on the write mode signal from the timing generating circuit 1. In this manner, different image data can be simultaneously developed to the RAMs 4, 5.

Title: Clock-system memory
Inventor: ANDOU TOSHISHIGE
IPC: G11C11/4076
Filed: 1979-03-20
Abstract: PURPOSE: To obtain a memory having a high-speed read access time by providing a pre-sense driving circuit to maintain a fixed delay time between signals on the word selection line and the sense clock line.  
     CONSTITUTION: Memory matrix 10 includes plural memory cells 11, and each cell is connected to word selection line 12 and bit lines 13 and 14. When chip enable signal CE is logic 0, the voltage level of bit lines 13 and 14 are made equal to VCC. Signal CE is set to logic 1 just after address signals A 0  to A 6  pass through decoders 33 and 37, and line driving circuit 31 generates a line selection signal onto word selection line 12, and simultaneously, row driving circuit 35 generates a row selection signal onto row selection line 30. Since pre-sense driving circuit 40 is clocked by the same signal CE and generates a sense clock signal delayed synchronously with the word selection signal onto the sense clock line, the access time can be shortened.

Title: Production of optical waveguide
Inventor: AKITA OSAMU
IPC: G02B6/12
Filed: 1990-02-13
Abstract: PURPOSE:To obtain the optical waveguide having a preferable mode field shape without increasing a propagation loss by immersing a substrate diffused with a metallic element into a melt dissolved with the salt of an alkaline earth metal element, thereby diffusing the alkaline earth metal element near the surface of the substrate. CONSTITUTION:The diffusion of the alkaline earth metal element, such as Mg, to lower a refractive index is executed by immersing the substrate 1 into the melt 13 of the alkaline earth metal element. Namely, the substrate is immersed into the salt bath contg. the ions of the alkaline earth metal element to diffuse the alkaline earth metal element from the molten salt into the substrate. Since the diffusion treatment can be executed at a low temp. by adequately selecting the salt to constitute the melt, the rediffusion of Ti is minimized. The production of the mode field having a desired shape with good controllability is possible in this way and the high-quality optical waveguide of the low propagation loss is produced.

IPC: G01R29/18
Filed: 1988-02-15
Abstract: PURPOSE:To simplify the constitution of circuits and to improve reliability by providing two detecting means, OR circuits, and detecting circuits corresponding to every two different phases. CONSTITUTION:If a fuse 21 blows out, the voltage between R and S phases is not applied and photodiodes 13 and 14 of a photocoupler 11 do not emit light, so that the phototransistor 17 of the photocoupler 11 is still off. A photocoupler 12 operates normally, so when the phototransistor 18 of the photocoupler 12 turns off, both phototransistors 17 and 18 turn off and the wired-OR output between the output signals of the phototransistors 17 and 18 goes up to a high level, so that a capacitor 25 is charged with the output. Then the voltage across the capacitor 25 reaches the reference voltage of a reference voltage source 28, the output signal of a comparator 27 falls to a low level. This low-level output signal is sent out as an open-phase detection signal.

Filed: 1980-03-17
Abstract: PURPOSE:To remove the limit of the maximum operating frequency of the circuit, by picking up the feedback signal from before n bits so that the delay time of the feedback can be neglected and making feedback with a delay, in a binary sequence circuit in which a plurality of FF circuits are in cascade connection. CONSTITUTION:FF circuits FF11-F13 are in cascade connection, the feedback signal is picked up from the output of FF11 and FF12 and it is fed to the delay line DL1 from the OR gate circuit G12, and delay is given by Td1 corresponding to one- bit's share and feedback input is made to the 1st stage FF11 of FF circuit. In comparison with the case that both the outputs of FF2, FF3 in FF circuit are fed directly back to FF1 conventionally, the delay time at the feedback circuit can be neglected by the feedback point before one bit, and high-speed operation can be made up to the toggle frequency of FF circuit.

IPC: H01L21/30
Filed: 1986-02-19
Abstract: PURPOSE:To make it possible to improve alignment accuracy and to perform highly accurate printing of a pattern with high resolution, by forming a recess part in the upper surface of a wafer, making air between the wafer and a mask to escape, introducing atmospheric pressure or pressure higher than that in radial grooves, and returning the deformation of the wafer to the original stage. CONSTITUTION:In the upper surface of a wafer mounting stage 20, a plurality of concentric grooves 3 are formed, and two radial grooves 2 are formed from the vicinity of the center to the inner side of the outer edge. The two radial grooves 2 are formed at symmetrical positions with respect to the center C. Each radial groove 2 is communicated to a vacuum source by way of a through hole 4. Each concentric groove 3 is communicated to a vacuum source by way of a through hole 14. Vacuum pressure is applied in the radial grooves 2 and the concentric grooves 3 by way of solenoid valves 8 and 18. Gas between a wafer 5, which is deformed adequately in a recessed shape, and a mask 6 is made to escape at the part of the radial grooves 2, and the yield of a gas trap is prevented. At this time, since the width of the groove is small at the part of the concentric groove 3, the wafer 5 is hardly deformed. Thus, the adhesion degree between the mask 6 and the wafer 5 is improved, and highly accurate pattern printing with high resolution can be performed.

Abstract: PURPOSE: To prevent processing from being delayed by any reason like a busy communication line by efficiently utilizing the line to be used for various kinds of processing. CONSTITUTION: Communication lines #1-#8 allocated for processing to receive a slip image and to recognize characters with the facsimile, for example, communication lines #9-#1 6 allocated for receiving PB data and communication lines #17-#24 to be used for the transmitting processing of a confirmation statement are previously allocated for several lines. Then, a line using condition measuring part 25 measures the using conditions of respective communication lines for just preceding fixed time. A communication line allocation control part 21 retrieves the idle line from such using conditions and allocates that line to a processing part on the high using conditions. When it is previously known that the change of using conditions is fixed corresponding to time zones, the lines at the rate set for each time zone are allocated to processing parts 22-24.
